Heath Nash is a designer that plays with materials until he finds the right inspiration to create the products such as the Flower ball. He believes in the saying “one man’s garbage is another man’s treasure” He tends to take advantage of Product Life Cycle. Since he is a product designer‚ he focuses his design work on how to reduce the global pollution. Even though his works are made of plastic‚ he would turn a product already made and turn it into a completely different work. How Heath Nash uses

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

1.1 INTRODUCTION: The human ear can hear the sound waves between 20 Hz to 20 kHz. This frequency range is known as “Audio Frequency Range”. The sound waves having frequencies above this audible range is known as “Ultrasonic Waves” or “Supersonic Waves”. Supersonic waves have the velocities higher than the velocity of sound i.e. more than 1200 km / hour. Ultrasonic waves can not be heard by a human being but a cat or dog may hear them. The wavelengths of ultrasonic waves are very small as

Experiment 112-5 Thin Film Interference Introduction When two waves of equal intensity combine‚ the intensity of the resulting wave can be anywhere between zero and four times the intensity of the individual waves‚ depending upon the phase difference between them. When they are in phase (the maxima coincide with maxima and the minima coincide with minima)‚ maximum intensity results. When they are exactly out of phase (the maxima of one wave coincide with the minima of the other wave)‚ the
